Pilot Project of Virologic and Immunologic Correlates of GALT Immune Reconstitution Following Raltegravir Therapy

HIV Infections Clinical Trial

Official title: A Pilot Project of Virologic, Pharmacologic and Immunologic Correlates of Gastrointestinal-Associated Lymphoid Tissue Immune Reconstitution Following Raltegravir Therapy

Status Completed

Clinical Trial Summary

This research is being done to study how the immune system in the small intestine improves after taking antiretroviral (anti-HIV) medications. The main purpose is to measure the increase in the numbers of immune cells in the intestine to see if one type of HIV medication gives different results than other types of HIV medications.

Clinical Trial Description

While the world-wide AIDS epidemic continues to impact millions of individuals, effective anti-HIV medications have substantially reduced morbidity and mortality for those patients able to adhere to combination regimens. Despite improved survival, durable virologic suppression, and increases in peripheral CD4+T-cell counts in patients receiving potent antiretroviral therapy (ART), immune reconstitution remains incomplete as measured by a number of additional surrogate markers. Perhaps critically important among areas of apparent incomplete immune recovery is the gastrointestinal-associated lymphoid tissue (GALT), where CD4+T-cells repopulate very slowly, if at all. Raltegravir is a new ART agent from a novel class of HIV inhibitors, integrase inhibitors, that results in rapid suppression of HIV and recovery of peripheral CD4+T-cells. This project proposes to examine whether volunteers receiving raltegravir recover GALT immune cells more completely than those taking comparator ART. ;
